Just felt like doing some raytracing that day so I took an old 3d project and turned it into a simple 'interactive' raytracing thing. It's interactive while it's small enough and only until you increase quality :). Just doing some simple spheres, polygons, point lightsources brute force 'global illumination' and blurred reflections. The plan is to use it to play around with some advanced technics some day.
Played around some more and tried some soft shadows... just sphere luminaires... had to remove reflections and specular highlights for some reasons ;)
This time with soft shadow and specular highlights and Reflections
